According to wiki, it is the largest in America - not the largest in the world.
That's probably why I havne't heard of Larry McMurtry - people who win literary prizes write the kind of things that bore the hell out of me.

I think the most fascinating thing for me in Texas was one 4th July I spent there. I was incredibly fascintaed. It was on some sort of smallholding where a group of people lived in trailers. All the girls had babies and they looked 18 years old.
The men had all traveled internationally, and they burnt about $2000 worth of firecrackers.
The entire thing blew my mind.
